Assuming Form1 creates and displays the Form2 instance, the simplest option would be for Form2 to raise a custom event when the values change. Form1 would subscribe to that event, and update its own values accordingly. Alternatively, Form2 would need a reference to the instance of Form1, and would call a public method on the form to update the values. You'll probably want to use an interface for the reference so that the implementation isn't tied to a single concrete class. Or you could use the Mediator pattern. Form2 would publish a message when its values changed. Form1 would subscribe to that message and update its values accordingly.
